(a) Before a public school employer enters into a written agreement with an exclusive representative covering matters within the scope of representation, the major provisions of the agreement, including, but not limited to, the costs that would be incurred by the public school employer under the agreement for the current and subsequent fiscal years, shall be disclosed at a public meeting of the public school employer in a format established for this purpose by the Superintendent of Public Instruction.

(b) The superintendent of the school district and chief business official shall certify in writing that the costs incurred by the school district under the agreement can be met by the district during the term of the agreement. This certification shall be prepared in a format similar to that of the reports required pursuant to Sections 42130 and 42131 of the Education Code and shall itemize any budget revision necessary to meet the costs of the agreement in each year of its term.

(c) If a school district does not adopt all of the revisions to its budget needed in the current fiscal year to meet the costs of a collective bargaining agreement, the county superintendent of schools shall issue a qualified or negative certification for the district on the next interim report pursuant to Section 42131 of the Education Code.
